To all whom it may concern:

Be it known that I, LESTER P. THoMrsoN, of Phelps, Ontario county, NewYork, have in vented a certain new and useful Improvement inHilling-Plows; and I do hereby declare that the following is afull,clear, and exact description of the same, reference being bad to theaccompanying drawings, in which Figure 1 is a plan of the plow. Fig. 2is a side elevation of the same. Figs. 3, 4, and 5 are detail views,showing the means for uniting the mold board with the beam. Fig. 6 is anelevation, looking on the inner side-of one of the wings, and showingthe means for attaching the adjustable wings to the mold-board. Fig. 7is aplan View of Fig. 6. Fig. 8 is a vertical cross-section, enlarged,in linear a: of Fig.

7. Fig. 9 is an elevation of the bearing D, looking on the inner side.Fig. 10 is an elevation showing the ratchet-teeth on the inner side ofthe mold-board, against which the bearing D rests.

My improvement relates to billing-plows for cultivating between rows ofplants, and is of that kind where wings are used attached to the rearends of the mold-boards, and operating to throw the dirt around theplants. Such wings have been before used, and I do not claim them,broadly; but my invention consists in a new means for attaching them, ashereinafter described and claimed.

In the drawings, A shows a metallic beam, which is curved down in therear and forms the standard for attaching the mold-board.

B B is the mold-board, which is doublewinged, so as to throw the dirtover on both sides. It is cast or formedin one piece,and is attached tothe standard of the beam by the following means: The standard is'formedwith an offset socket or cavity, a, and the moldboard is formed with astraight lug, b, which extends centrally and longitudinally and rests inthe socket or cavity a, and is secured in place by a screw-bolt, c. Thisis shown most clearly in Figs. 3, 4, and 5. By this means the mold-boardis brought centrally with the standard, and the parts are secured in thesimplest and strongest manner, and but a single bolt is required. Thelog is so firmly seated that it can never get out of place. By thisarrangement a shoulder is left on each side of the standard, whichpresents the same appearance in looking down on top.

0 G are two wings hinged at the rear ends of the mold-board and capableof adjustment out and in at the rear, also up and down vertically,either bodily or at diii'erent inclines, by the means hereinafterdescribed. The wings are attached on the inner sides of the mold-boardsby means of hinges d cl to bearings D D, which in turn are attached tothe mold-board by screw-boltsff. The bearing is provided with a slot, 9,through which the bolt f passes, and by this means the bearing can beadjusted higher or lower, carrying the wing with it bodily. Thisvertical adjustment of the wing is indicated by the dotted lines in Fig.2. The wing can also swing on its hinge out and in, and this lateraladjustment isindicated by the dotted lines in the plan view, Fig. 7. Onthe inner or back side of the bearing D is a spur or point, h, -on eachside of the slot, Figs. 8 and 9, and on the face of the mold-board, overwhich the bearing rests, are

sets of ratchetteeth k k, Figs. 8 and 10, into which the spurs strike.By this means the bearing can be held at any height when clamped by thebolt, and be prevented from twisting or turning out ofplace. By settingthe spurs into different teeth of the ratchets the bearing can also beset in a somewhat inclined position, so that, in addition to theadjustments of the wing O, as before described, the wing can be adjustedso that it will stand at an incline with the rear end the highest, asindicated by the dotted lines in Fig. 6. By means of these several adjustments of the wings almost any desired kind of hill may be producedaround the plants-steep, flat, or otherwise. To make a steep hill thewings are raised at the rear end. To make a flat hill they are lowered.Toadjust the wings to wide rows they are thrown farther apart, and tonarrow ones they are brought together. on the inner sides of themold-board, and not at the rear ends or outside, all clogging isprevented, the weeds passing off without obstruction.

By hinging G is a block or cross-piece attached to the IOO ping pasteach other, provided with adjusting-holes m m, through which passes abolt, n, securing them to the block G. By this means the lateraladjustment of the wings is produced.

I I are straps attached at their top to the handles and at their bottomto the bearings D D by means of the screw-bolts f f, which pass throughholes 1) p of the straps. By this means the handles are adjusted higheror lower.

Having described my invention, I disclaim simply and broadly the use ofwings hinged to the rear end of the moldboard; but

I claim 1. In a billing-plow, the combination, with wings hinged at therear end ofthe mold-board, of the bearings D, secured on the inner sideof the mold-board, to which the wings are hinged, said bearings beingslotted vertically and secured by bolts and provided with teeth orspurs, which engage with ratchets or depressions on the inner sides ofthe mold-boards, as shown and described,and for the pu rpose specified.i

2. In a billing-plow, the combination of the wings C, the hinges d, thebearings D, having spurs on the back engaging with ratchetteeth on themold-board and provided with longitudinal slots, through which pass theclamping-bolts f, the straps I, connecting the handles with thebearings, and the cross-straps H H, connected with the wings, lappingpast each other and secured by a screw-bolt, as shown and described,andfor the purpose specified.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
